The minimal size any IP-stack has to be able to handle is 512 bytes. Normally, 
modern IP stacks will handle packets up to 4096 bytes and possibly larger 
packets (with correct fragmentation and rejoining). But this depends on the 
IP stack that's used to send and to receive the packet.

Anyway, a maximum size of 255 bytes is certainly not true for UDP packets.
